- The in-house CFD code NUMBERS is used for evaluating the performance of the intake. The solver NUMBERS is a structured in-house code which solves the Euler and the Navier-Stokes equations in the compressible flow regime. The turbulence models implemented in the code are Baldwin-Lomax, Spalart-Allmaras /1/ and Menter SST /2/ models. The viscous derivatives are calculated by the least -square method. The equations can be solved by predictor-corrector MacCormack scheme, central-difference Jameson scheme /3/ and upwind H-CUSP scheme

Fluid dynamics is a very complex subject.
However, nicely explained.
I didn't even triad to explain FD here, it's one of my favourite subjects, I restrained my self to go into details at various point, ppl call it boring, otherwise i was in a mood to explain the whole boundary layer concept, and what a stream line and turbuce flow does to the intake air😄😃
@@Amitraaz where and how can I learn about FD ?? Please tell me. 🙂
@@Amitraaz and is it your 2nd and back up channel ??
DSI intake is an essential component. Its good to know about OPRDs. There's always tradeoff between using DSI and not using it. Another great video. F22 was designed to go WVR first, but switch to BVR if needed. The USAF required another jet to fill the gaps of F22, a jet than complement it and help in BVR. F35 has a single engine producing a dry thrust of 128KN. It's a significantly larger engine but it is still slow. Thus you would need a DSI. F22 can reach confidentially estimated mach numbers up to 2.6. At such speeds, you need a larger intake and since its a twin engine jet, DSI will only hinder its speed at High Bypass. Its designed to go fast, but yes DSI would help in expelling the intake air at high speeds too. Thus AMCA design uses best of both world technologies

India should set up public fund for research and development on kaveri engine 😁😁😁 like if you will donate
Until India develops own aircraft engines, India will be forced to depend on other nations. India must not give up. India must keep on working on indigenous engine and if possible buy engine technology in lieu of huge defense deals. India must learn from Japan.
I think kaveri engine was completed,right?
@@shaileshkumar6010 nah man. It's a joke among the people who work in the defence field.😂
@Gaming Zone with GOD hmm,I think if india takes help with France,it would be completed,since they are one of the leading defense manufacturers from a long time,so they definitely know and if possible,for radars and other technical equipment we can take Israel's help(if we can't do it alone)since they are leading in smart technology.
@Gaming Zone with GOD only time will tell my dude. The Indian military does not have that much faith in the Government run industries. They take too long to develop and when they do deliver it's sub parr. Allowing private companies to compete with Agencies like DRDO will greatly benefit the forces.
@Gaming Zone with GOD you just prove my. it took DRDO god knows how many years to develop an engine which is not even functional for its proposed function
The way u explain the difficult engineering term in a very simply way is amazing
Wow, what is your qualification? Your very good at heat transfer and fluid dynamics,I appreciate your work 😍.

You always surprise with a depth study of new things coming up...
Now i stay assure not to study from my own end, coz i know you will come up with that😊
An easy to understand perspective on inlet design. Thank you Amit.
Very well described. DSI K Kyi article dekhe but kaafi chize aapki video ne clear kr di
Bro you are actually utilising the lockdown period well. Keep up the good work. Subscribed
how?
@@defencedecodeOfficial By making such knowledgeable videos....
A very interesting and informative presentation. PL. keep us enjightened on such things.
Your work is indeed pretty amazing.
I love your analysis. Very technical
Make video on Japanese Jet Engine xf 91 made within 10 year with dry trust of 108Kn.
Not 10 years it took them 23 years, design and development started in 1995 and 1st prototype of engine was delivered in 2018 on top of that Japanese had an experience of building Low pressure components for High bypass ratio turbo fan engines for commercial airliners in collaboration with General Electric, Pratt & Witney & Rolls Royce where as we have never worked on any jet engine be it low bypass or high bypass be it in collaboration or solo, Japans partnership in defense technology with the west all these years have helped them a lot to acquire know how of defense tech, we were busy being Soviets puppet at that time who hardly ever transferred any technology to us or set up any joint venture to produce defense hardware in India, comparing Japan who has access to high tech western tech with India is like comparing apple's with oranges however we too need to have our indigenous jet engine there's no question about it.
Thanks
Technologically India is now a member of elitest group of technologically most advanced countries. India produces cutting edge space products with highest level of technology at cheapest possible price. Such level of precision and prefection is not seen in our western counterparts.
As our drdo chief Dr G Satish reddy always makes it clear that India is self reliant and has become strong in area of missile technology, radar technology, sonars, electronic warfare systems, displays and guns. Our tejas is way ahead in terms of technology when compared to any chiense or russian jet. Russian technology is third grade but cheap while chiense weapons are expensive paper weight copied from russia. Many many more futurstic weapons are being developed by drdo. One of them being laser weapon. Drdo has already developed a 250kw laser weapon which is undergoing testing. And is being taken to more advanced level. India deployed its laser weapon to protect trump during his India visit. China doesnt even have an anti icbm defense system. While Indias anti icbm defense system is way ahead of american thaad. Today no country in the world can sneeze in direction of India let alone harbour the thoughts of attacking us. Even though china had s400 yet they chickned out of doklam. There are many examples where american weapons have been found wanting.
@@doom2000000 wow......do they pay you for writing all that bs?
@@leaderbad1548 its hard facts. Better get used to it.
Sir aap hi Ek Aise ho jinko pure basic knowledge he Jis topic per aap videos banate Ho bake to sab paper reading kr dete hein
Thanks Amit for reverting to my question on previous video..
Thank you for your awesome content.
Those who thinks that , without engine it is nothing ! Just check the Whole Tejas programme ! Tejas was delayed due to a continuous design phase & not a fixed design . Engine supply from General Electrics was on time, but due to changes in design led to delay of the programme . Although engine is necessary ! But completing & finalising & fixing a design is a major step towards development of a fighter jet ! & After this design & RCS testing we are just left with work of engine Development & we will surely build our own Indigenous Engine .
Can y'all put English subtitles that would help thank you very much!
Wow wt a knowledge...!!! Explanation too gud...this subject is your interest of area
Wow, Boundary layer- technical sound description
Bhai, mast knowledge hai aapko♥️♥️
Very good explanations 👌👍
Very nice video and very helpful information.
Great knowledge bro, keep it up
Very much informative
Good technical explanation.
You deserve more subscriber🖐🏼
So they used f 35 technique, AMCA looks like hybrid of f 22 and f 35..
It is, but frontal nose cone aspect are elongated more. It's nose cone is larger in comparison to the two. Meaning we can fit a larger AESA radar with higher number of TR modules and still be able to fit more sensors. It also helps is generating lift at low speeds and reduce air drag much better than F35 as per initial study done by ADA.
@@RahulYadav-nk6wp larger AESA radar needs a powerful engine...
@@Witcher1989 that why we r using F-414 EPE Engine which produces 118 KN of thrust for AMCA
@@mihirsrivastava1113 let's hope AMCA doesn't face the same fate as Tejas
@@Witcher1989 well AMCA will not face the issue bro
great video nice scientific knowledge
sir, how does the su-57 cope up with this problem?
and in the past, soviet jets like the mig-31 could achieve speeds upto mach 3. Did they use the same concept?
Su-57 has ramps + front looking LERX
@@firestarter9784 LERX are used mostly for low speeding, sustaining high alpha at subsonic speeds or lower and can be used as air breaks. Yes could divert air away form air intakes, but it does nothing much than that. RAMPS, yes they do help channeling air away during high bypass requirements when achieving higher mach numbers.
@@RahulYadav-nk6wp what is the range of su30 mki radar
@@RahulYadav-nk6wp then you hav'nt seen the LERX of su-57
dipayan saha 400 km
Nice explanation.
Excellent information
Thanks sir ji.
Waah good explanation...🙌
Super. Nice explanation with graphics for easy understanding. Tks. But sir a common man will not be so inclined to go through thus technicality. But appreciate your efforts to make this video. Jai Hind.
Can you make a video on Japanese Jet Engine ? We don't have much info available on it right now, Amit. Thanks for sharing so much technical info on AMCA.
AMCA needs 5th gen indigenous engine that can supercruise without afterburner.
And Does the problem related Air intake on LSP fixed ?
Yeah in that case we won’t even get the aircraft by 2050
Both hi bahtaeen
Boht achi video hai
Ab to yeh ek hybrid jet lag raha Hain F-22 & f-35 ka
F22 jaisa hona chahiyae
Ye sirf representative images hai. Actual design model 2020 ke end me ya 2021 ke start tak reveal hoga
@@piyushjoshi01 defense decode ne post ki hai, kuch to similarities hoga
Great video
U deserve more n more subscribers bro..bcs ur videos r awsm .. n jai hind
Nice informative Vdo 👌👌👍👍👍
NICE VIDEO BRO
Amitji namaskar. You explain very well all the technical details. How much percentage did India achieved in the jet engine. Will we succeed in a short time or is it going to take longer.
is it possible to have adjustable single bump like ramp acuated through spring loaded assembly
Amca kaa speed kya hoga ...or yaa kinthay fit per fly kra gaa
Bhai....f-22 me horizontal stabilizer kun laga h. or vo concept AMCA me use kun nhi kiya h.
Plz ans how much rcs of Tejas is going to e ffected by mid air refueller prob
Very nice information bro
Why the engine outlet is not covered just like in f22? It may increase RCS.
Sir u r ultimate
What about difference in air density. How would it's variation affect the aircraft
love 😍
Is su 57 is good option then mmrca 2 ???
Bhai ye batao ki jo iske engine ki design hai wo to round shape to ye to kam stealth hoga??
Very nice
Kiya bat sir good job
It depends on engine then...
How can an aircraft have a fixed air intake, since air density varies with altitude even within specified service sceling..?
the bump is designed purposely, which generate shockwave and slow down the air. However there is some limits on speed.
Can you please compare the RCS of AMCA with f 35 and f22
What is the final design of amca many different designs pictures of amca r floating I'm confused what is final design? please reply thanks
Very interesting and informative vedio.
Sir why kaveri engine is not successful. If kaveri programme fail then we we make purvown jet engine for aircraft
Which fighter jet is India buying for MMRCA .114jet are about to buy .
Pls make a video.of engine exhaust, is it like F22?
I personally like this step
Bhai itna analysis app aeronautics padhee ho kya...
AHCA ka Koi plan hai
Liked it man.... You are good..... if possible, Please help us know how rafale were better option than tejas.... Apart of single and dual jet engine.....
If tejas's air intakes are not upto the mark then as per the pictures online mk2 has the same intake , we cud have/shud have designed it as DSI. What is ur take on this?
Can u make a vedio on the comparision between AMCA AND F22
Bro what if the amca DSI is designed for Mac 2 . Is it possible or not kindly answer.
Sir what will be top speed of amca
Is it 2655 kmph ?
Amit g Namashkar... What about multiple intakes? which open at different air requirements ... This will also reduce radar signature!! These can be in shape of tubes infused in body starting from nose section to engine... Im not a engineering guy but out of curiosity!!
Range of infrared sensors, information integration, and radar range can over take such limitations.
Good luck 👍👍👍
does it affect the stealth.?
How does AMCA have engine nozzel stealth like f22 has ??????
Question? Why our AMCA has no smooth surface like extremely flat design at the Top, core section of F22, I assume it due to reducing drag?
Design to be revealed by end 2020. These are just representative images
Very nice 👍👍👍👍👌👌👌👌
Which type of air intake in j20
Amca ko kiya bird strike se bachane ke liye inprove kiya jaa raha hay?
Why do we want to save money and take more risk with limiting the max speed or sending more vibrations to the engine ?
Bhai AMCA ka engine ander hoga ya bahar?
Air intake design dictates up to which Mach number , inlet flow can be decelerated without flow instability .
Maza aa gaya
Defence Decode, what if we make the bump with flexible composites? hmmmm...... then we can make the DSI intakes work for different Mach values.
Any latest updates on super sukhoi stealth coating . And any update on Sukhoi T-60 pigeon .
Bro AMCA me Kon sa radar lg ra h ????
Tejas mk 2 में केसा होगा
Sir AMCA looks like J 31. How it is different from J 31 in it's design?
both are similar copy cats………
I always check the progress of AMCA and TEJAS .i m just curious whether is this the world-class aircraft? , better maneuver compare to F22 and Sukhoi 35 ?.is this the best composite material used better stealth than other stealth aircraft available ?
Su 57 is a million moons away from being a 5th gen fighter jet.
Russian technology is third grade but cheap while chienese weapons are expensive paper weight copied from russia. Hardly anyone buys russian arm these days as they are unreliable and require a lot of constant service. China is only customer with a lot of money.
As our drdo chief Dr G Satish reddy always makes it clear that India is self reliant and has become strong in area of missile technology, radar technology, sonars, electronic warfare systems, displays and guns. Our tejas is way ahead in terms of technology when compared to any chiense or russian jet. Tejas rcs is 0.5m2 and tejas mark 1a will have even lesser rcs. While sukhoi rcs is 5m2.. sukhoi will be easily detected by radars at very long. This is just one example of how superiority of tejas.
Bhai iski speed kitni hogi
👍👍
Sir you well knowledge aeronautical and physic ...
You may be join DRDO or GTR
When can we see AMCA from drawing board to final bird?
AMCA Ioc aircraft after 2025
I cnt wait..
I got some questions.... Please answer kardijiya......
WHY AMCA??? Why not AHCA (Advance heavy weight combat Aircraft)
If you are spending in Stealth then why not make a Heavy weight Aircraft with Long range and better weapon package?
F-22 can carry 8 internal missiles and AMCA only 4?
AMCA Having a very week BVR Missile compared to F-22 and F-35?
AMCA Have less range than F-22.
(It makes no sense to use Stealth fighter near you border only, if it cannot even go deep in enemy territory where actual defence are installed.
If it will come to China we will not even be able to make a dent in their main land.)
I know you might argue that we never plan on hitting Main land China, we will only defend our Border and etc.etc.
But my question if you are spending money than your weapon should have the capability to take out your enemy entirely.
If you will do it or not will depend on Army and the National policy.
In this times when war rarely happens, we must focus on superior technology rather than human Skills, which will be rarely be tested in Air Combat.
Design wise (Even though not finalised) it’s so much inferior to F-22 or F-35?
And there is no comparison of Engines. (Very inferior engines used in AMCA)
What’s the point of making stealth fighter if it cannot even maintain a standard set by F-22 10 Year's back?
For India maybe we should have focused on suppressing enemy defence system rather than stealth.
I am only stating my genuine concern hope you can find answers to these question.
And hope fully our AMCA will have at least better Stealth than Su-57. Because pretty sure it will be inferior to F-22 when it comes to stealth.
(I So much wish that my concerns are proven wrong by DRDO and Companies getting involved in this Future project of India)
Bhai top 20 fighter jet according to RCS ki vedio banao
